nodes

Obtain a list of nodes from a transferable.
If there is only a single node in the transferable, this will just return a singleton
array like NodeTransfer.node(java.awt.datatransfer.Transferable, int).
If there is a multiple transfer (of at least one element),
each element of which
contains a node, then an array of these will be returned.
If neither of these things is true, null will be returned.

This is a convenience method intended for those who wish to specially support pastes
of multiple nodes at once. (By default, an explorer will
fall back to presenting each component of a multiple-item transferable separately when checking for paste
types on a target node, so if you have only one paste type and it makes no difference whether all of the nodes
are pasted together or separately, you can just use NodeTransfer.node(java.awt.datatransfer.Transferable, int).)

If you wish to test for cookies, you should do so manually
according to your specific logic.
